They are the stock Mach 1 brakes and are identical to stock Cobra brakes except they dont say cobra. The calipers are no different, paint or otherwise from the Cobras. They will be fine and are much cheaper than most places. Mustang Tuning has the cheapest kit other than this one. Theirs is $400 + 5% off and free shipping if you use stangnet code. But the MT ones say COBRA.
